Arthur's Computer Adventure is a Living Books educational game based on the book Arthur's Computer Disaster by Marc Brown. The book's plot is that Arthur has been playing his new computer game, Deep Dark Sea, a lot. When Arthur's mom leaves to her office, Arthur invites Buster over. The two of them fight over who should play, and think they broke the computer when it shuts off. They try everything to try to fix it, but they can't, and Arthur offered D.W. all his desserts for a week so she wouldn't tell. When Arthur's Mom gets home, Arthur is forced to admit what happened and learns his lesson when he is grounded from the computer for a week.
The game also offers five mini-games to play. Toy Copter is a game where you put out fires in a toy helicopter. D.W.'s Store is a game where you earn money at D.W.'s Cafe to help her buy accessories for her toys. Treasure Hunt is a board game where you have to match words with the correct picture. Frankenfish allows you to combine different fish species together while learning about each one. Finally, there is Deep Dark Sea, where you avoid creatures like sharks and jellyfish while trying to find hidden treasure. This is the game Arthur plays in the storybook.
